Secure the latch, sleeve and screw and check for smooth secure operation. Note: older latches come in left and right configurations. Replacements may be used either way.
Automotive Latch Replacement:
This latch is secured to un-branded vent glass with two screws through holes in the glass. (The screws are actually held by a threaded binding post on the backside of the glass.) In addition, there are various spacers and sleeves that also must be used in this assembly. Thus, it is important that the vent glass be pushed as close to the mullion as possible during replacement. This will keep the pieces on the backside of the glass from coming loose, which could make latch replacement more complicated. Remove the two screws inside the latch housing using a suitable Phillips head screwdriver. Discard the defective latch. Place and align the new latch and the flat handle spacer with the binding posts in the holes through the glass. Secure in place with the screws provided. Be sure the screws are tight, but do not use a power screwdriver. Tighten by hand. Check for ease of operation and secure latching.
